Disclaimer: I have no idea if this are indeed the correct answers. I just solved the exercises like this. I think that they are right though.

I have added my own code to this gist. It is ugly as hell, just like you can expect from code created in a contest like this.

Beautiful Strings

Difficulty: easy

It is simple to see that a greedy solution is good enough.

Libraries

960 Grid System - An effort to streamline web development workflow by providing commonly used dimensions, based on a width of 960 pixels. There are two variants: 12 and 16 columns, which can be used separately or in tandem.
Compass - Open source CSS Authoring Framework.
Bootstrap - Sleek, intuitive, and powerful mobile first front-end framework for faster and easier web development.
Font Awesome - The iconic font designed for Bootstrap.
Zurb Foundation - Framework for writing responsive web sites.

Guides

Libraries

jQuery - The de-facto library for the modern age. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers.
Backbone - Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface.
AngularJS - Conventions based MVC framework for HTML5 apps.
Underscore - Underscore is a utility-belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js (or Ruby), but without extending any of the built-in JavaScript objects.
lawnchair - Key/value store adapter for indexdb, localStorage

Internet Scale Services Checklist

A checklist for designing and developing internet scale services, inspired by James Hamilton's 2007 paper "On Desgining and Deploying Internet-Scale Services."

Basic tenets

Does the design expect failures to happen regularly and handle them gracefully?
Have we kept things as simple as possible?

Better SSH Authorized Keys Management

A seemingly common problem that people encounter is how to handle all of your users authorized_keys file.

People struggle over management, ensuring that users only have specific keys in the authorized_keys file or even a method for expiring keys. A centralized key management system could help provide all of this functionality with a little scripting.

One piece of functionality overlooked in OpenSSH is the AuthorizedKeysCommand configuration keyword. This configuration allows you to specify a command that will run during login to retrieve a users public key file from a remote source and perform validation just as if the authorized_keys file was local.

Here is an example directory structure for a set of users with SSH public keys that can be shared out via a web server:

Legend

🏆 - Best Of

Fiction (24)

John Green - The Fault in Our Stars (Джон Грийн - Вината в нашите звезди) 🏆
Stephen King - 11/22/63 (Стивън Кинг - 22 ноември 1963) 🏆
Suzanne Collins - The Hunger Games (Сюзан Колинс - Игрите на глада) 🏆
Aldous Huxley - Brave New World (Олдъс Хъксли - Прекрасният нов свят)

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
